Most common Cu fertilizer. Formula: CuSO4.5H2O (24 percent Cu). It comes in particle sizes varying from fine powder to granular. A less hydrated form, CuSO4.H2O, contains 35 percent Cu. A poisonous blue crystalline copper salt sometimes used in fish culture as an algicide or in control of parasites and diseases. (FAO. 2006.

A biophysical model is a simulation of a biological system using mathematical formalizations of the physical properties of that system. Such models can be used to predict the influence of biological and physical factors on complex systems. (Mehmet Yavuz, Fuat Usta. Importance of modelling and simulation in biophysical applications[J]. AIMS Biophysics, 2023, 10(3): 258-262. doi: 10.3934/biophy.2023017)
A woodland management system for non-coniferous forests. Coppice regeneration is mainly through asexual reproduction, thus exploiting the capacity of certain forest species to generate sprouts (suckers) at the base of the trunk (stump) once it is cut. (European Climate, Infrastructure and Environment Executive Agency. Sustainable and multifunctional management of Umbria coppices https://webgate.ec.europa.eu/life/publicWebsite/project/LIFE99-ENV-IT-000003/sustainable-and-multifunctional-management-of-umbria-coppices)
A silvicultural tool consisting of cut back trees or shrubs to ground level periodically to stimulate growth. The regrowth can be selected to facilitate forest regeneration. (Grazing with trees – A silvopastoral approach to managing and restoring trees. FAO Forestry Paper, No. 187, FAO, 2022 (https://doi.org/10.4060/cc2280en).)
Dried meat of coconut. The dried flesh of coconut from which the oil is extracted. (Draft Definition and Classification of Commodities, W2979,FAO 1996.)
The act of coupling or bonding during sexual intercourse; the state of being joined during sexual intercourse. (Gordh and Headrick 2001, FAO/IAEA/USDA 2003)
A marina is a dock or basin with moorings and supplies for yachts and small boats. Marinas may be located along the banks of rivers connecting to lakes or seas and may be inland. They are also located on coastal harbors (natural or man made) or coastal lagoons, either as stand alone facilities or within a port complex. (https://en.wikipedia.org/wiki/Marina)
Note
A marina differs from a port in that a marina does not handle large passenger ships or cargo from freighters. In the UK the word marina is also used for inland wharves on rivers and canals that are used exclusively by non-industrial pleasure craft such as canal narrowboats.
Coral reef: A tract of corals growing on a massive, wave-resistant structure and associated sediments, substantially built by skeletons of successive generations of corals and other calcareous reef-biota.

Springer, Dordrecht. https://doi.org/10.1007/978-90-481-2639-2_63)
Borna disease virus (BDV) is an enveloped RNA virus that causes meningoencephalitis primarily in horses in Europe, but also in sheep, cattle, and a variety of other domestic and wild animal species. (Sykes, Jane. (2014). Vector-borne and Other Viral Encephalitides. 10.1016/B978-1-4377-0795-3.00027-2.)
Marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically live in compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. (FAOLEX. 2025. Glossary https://www.fao.org/faolex/)
